直流電機電樞反應的問題
　　1、直流電機的電樞磁場，對轉矩沒有貢獻；
　　2、直流電機的電樞磁場，對主極磁場是交軸去磁作用，負載大時電樞電流大，去磁作用越強；
　　3、直流電機的定子磁場，都安裝有換向極，換向極的勵磁電流就是電樞電流；
　　4、換向極的磁極方向與電樞磁場方向始終相反，互相抵消，這樣保證主極磁場方向不變，磁場不會因電樞反應而減��！
　　5、直流電機的電樞電流與勵磁電流分別控制并沒有優勢可言；而恰恰是交流電機的電樞電流磁勢與轉子電流磁勢互相抵消從而保持旋轉磁勢恒定有優勢！

一般來說，聲音清脆的磚密度大、強度高、吸水率較小，磚的質量較好；反之，聲音悶啞的磚密度較小、強度較代、吸水率較大，磚的質量較差。看：是用目測的方法來檢查釉面磚的表面質量。合格的釉面磚不應有開裂、夾層和釉面開裂現象；磚背面不應有深度為1/2磚厚的磕碰傷；磚的顏色應基本一致；距磚1米處觀測，好的釉面磚不應有剝邊、波紋、缺釉、棕眼，正面磕破等表面缺陷。比：對磚的方正和平整，我們可以采用比的方法來檢查。

　　3、安裝減速機時，應重視傳動中心軸線對中，其誤差不得大于所用聯軸器的使用補償量。
　　不采用鋼性固定式聯軸器，因該類聯軸器安裝不當，會引起不必要的外加載荷，以致造成軸承的早期損壞，嚴重時甚至造成輸出軸的斷裂。
　　快速處理減速機常見問題（一）減速機軸承室磨損減速機軸承室出現磨損，問題發生后，傳統方法難以現場解決，必須依靠外協修復，需要長時間停機停產，浪費企業寶貴的生產時間。
　　而且都是用金屬修復金屬，無法改變“硬對硬”的配合關系，在各種力的綜合作用下，仍會造成再次磨損。
　　高分子復合材料具有的粘著力，優異的抗壓強度等綜合性能，采用美嘉華高分子復合材料，可免拆卸、免機加工，快速有效修復軸承室磨損。
　　即無補焊熱應力影響，修復厚度也不受限制，同時產品所具有的金屬材料不具備的退讓性，吸收設備的沖擊震動，避免了再次出現磨損的可能。
